Welding Wikipedia. Welding is a fabrication process that joins materials usually metals or thermoplastics by using high heat to melt the parts together and allowing them to cool causing fusionWelding is distinct from lower temperature metal-joining techniques such as brazing and soldering which do not melt the base metal. Plastic welding is welding for semi-finished plastic materials and is described in ISO 472 as a process of uniting softened surfaces of materials generally with the aid of heat except solvent welding.
A constant voltage direct current power source is most commonly us. Plastic welding is welding for semi-finished plastic materials and is described in ISO 472 as a process of uniting softened surfaces of materials generally with the aid of heat except solvent welding. Anyone who is near arc welding needs to wear a special helmet or goggles because the arc is so bright.
It is predominantly referred to as hyperbaric welding when used in a dry environment and underwater welding when in a wet environment.
The associated N reference numbers second column are specified in ISO 4063 in the European Union published as EN ISO 4063. Along with the wire electrode a shielding gas feeds through the welding gun which shields the process from atmospheric contamination. Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal and the melted metals when cool result in a binding of the metals.
